HP 4100 manual Reassembly Notes

Reassembly Notes

Note: Installing a New Motherboard

∙If a RAM board is present, transfer it from the old motherboard to the new one:

∙Reprogram the BIOS IC—see the note below.

∙Store the serial number electronically in the new motherboard—see the steps below.

Note: Installing a New Bottom Case

∙Transfer these parts from the old bottom case to the new one:

I/O door, docking doors, and module latches (see the figures below).

Speakers.

∙Install a new regulatory/business card label.

∙Install a new serial number label and overlay—see the steps below.

∙Route the speaker wires so they do not get pinched or block screw holes.

∙Route the fan wires at the bottom of the opening next to the motherboard.

∙When attaching the IR PCA to the right frame, make sure the PCA is parallel with the back of the case.

∙Before installing the CPU module, assemble it into the bottom plate and attach the top plate. Then install the complete assembly on the motherboard. See the following caution.

Caution

∙Install or replace CPU module thermal pads that are missing or damaged. See the figures below.

∙Keep the CPU assembly flat while installing it. Press it down above the connectors at the right end. Otherwise, you could damage the connectors.

∙Install the two screws in diagonally opposite corners of the top plate.

Note

If you installed a new motherboard with a new BIOS IC, the IC contains only enough basic programming to boot the OmniBook. After installing the IC, you must reprogram it. Hewlett- Packard prefers that you program the IC with the latest BIOS—follow the directions carefully. You can download it from the OmniBook website (see page vi).
